9.3 Bitstring Operators...

PLC Designer IEC operator: Bitwise AND of bit operands. The operands should be of the

type BOOL, BYTE, WORD or DWORD.

Example in IL:

LD 2#1001_0011

AND 2#1000_1010

ST Var1 (* Result is 2#1000_0010 *)

Example in ST:

var1 := 2#1001_0011 AND 2#1000_1010

Example in FBD:

If you have a program step in the SFC like the following

and if you use 68xxx generators, please note the following: The allocation of the

value of the second input variable at the AND operator module to variable z will not

be executed ! This is due to the optmized processing in the SFC in case of value

FALSE at the input variable.
